ABSTRACT

The invention relates to a cosmetic composition for coating keratin fibers, comprising a cationic polymer, an anionic polymer and an aqueous dispersion of C 1 -C 6  alkyl (meth)acrylate. 
     The invention also relates to a process for coating keratin fibers which consists in applying the composition to the keratin fibers. 
     The composition leads rapidly to a uniform make-up result which has good properties of coating, lengthening and curling the eyelashes, as well as good staying power.

The present invention relates to a composition for coating keratinfibers comprising a mixture of film-forming polymers. The invention alsorelates to the use of this composition for making up keratin fibers, aswell as to a process for making up these fibers. The composition and themake-up process according to the invention are suitable forsubstantially longilinear human keratin fibers such as the eyelashes,the eyebrows and the hair, including false eyelashes and hairpieces. Thecomposition can be a make-up composition, a make-up base, a compositionto be applied to a make-up, also known as a top-coat, or, alternatively,a composition for cosmetically treating keratin fibers. According to oneembodiment, the invention relates to a mascara.

Compositions for coating the eyelashes, known as mascaras, generallycomprise at least one wax and at least one film-forming polymer. Amascara is typically used to deposit a make-up film on the eyelashes andcoat them. Published PCT Application No. WO-A-95/15741, for example,describes such compositions. Users expect these products to have good acosmetic properties, such as adhesion to the eyelashes, lengthening or acurling of the eyelashes, or, alternatively, good staying power of themascara over time, in particular good resistance to rubbing, for examplewith the fingers or fabrics (handkerchiefs, towels).

To give the eyelashes a lengthening effect, French Patent ApplicationNo. FR-A-2 528 699 proposes a mascara comprising waxes and a combinationof anionic polymer and cationic polymer. However, these compositions maynot allow optimum curling of the eyelashes.

One aspect of the present invention is to provide a composition formaking up keratin fibers, including fibers such as the eyelashes, whichmay apply easily and may provide for good curling of the keratin fibers.

The inventor has discovered that such a composition may be obtainedusing a specific combination of film-forming polymers.

More specifically, one aspect of the invention is a composition formaking up keratin fibers comprising at least one film-forming polymercomprising at least one cationic film-forming polymer and at least oneanionic film-forming polymer, characterized in that it comprises anaqueous dispersion of at least one C₁-C₆ alkyl (meth)acrylate nonionicfilm-forming polymer.

The composition according to the invention may apply easily and mayattach well to keratin fibers such as the eyelashes. It has been foundthat the make-up results such as the coating, lengthening, and curlingof the eyelashes may be obtained quickly and easily after applying thecomposition to the eyelashes. The make-up may be comfortable for theuser to wear, and it may be easily removed with conventionalmake-up-removing agents.

One embodiment of the invention is a process for coating keratin fibers,such as the eyelashes, comprising applying a composition as definedabove to the keratin fibers.

Another embodiment of the invention is the use of a composition asdefined above to curl and/or lengthen and/or coat the eyelashes, and/orto obtain a fast make-up, and/or a make-up which is easy to apply,and/or which has good staying power.

The expression “film-forming polymer” means a polymer which by itself,or in the presence of a plasticizer, leads to an isolable film.

The composition according to the invention comprises an aqueousdispersion of at least one nonionic film-forming C₁-C₆ alkyl(meth)acrylate polymer, such as a polymer derived from at least oneC₁-C₆ alkyl (meth)acrylate monomer. These polymers can be chosen fromC₁-C₄ alkyl (meth)acrylate polymers, such as copolymers derived from atleast one monomer chosen from C₁-C₄ alkyl acrylate and C₁-C₄ alkylmethacrylate. C₁-C₄ alkyl (meth)acrylates which may be mentionedinclude, for example, methyl (meth)acrylate, ethyl (meth)acrylate,propyl (meth)acrylate, and butyl (meth)acrylate. A copolymer derivedfrom ethyl acrylate and methyl methacrylate, such as the one sold underthe name DAITOSOL 5000 AD by Daito Kasey Kogyo, may be used.

The aqueous dispersion of nonionic film-forming alkyl (meth)acrylatepolymer can comprise polymer particles ranging from 10 nm to 500 nm insize. In another embodiment, the particles can range from 20 nm to 300nm in size.

The expression “aqueous dispersion of polymer”, which is generally knownas a latex or pseudo-latex, means a phase containing water andoptionally a water-soluble compound, in which the polymer is disperseddirectly in the form of particles.

In practice, the nonionic film-forming C₁-C₆ alkyl (meth)acrylatepolymer can be present in the composition according to the invention ina solids content ranging from 0.1% to 15% by weight, relative to thetotal weight of the composition. In another embodiment, the solidcontent can range from 0.5% to 8% by weight.

These polymers can be used in dissolved form or in the form of aqueousdispersions of solid polymer particles.
